npm RACCES: permission denied

When I run npm run deploy to deploy my blog, the error "Error: EACCES: permission denied" shows up. However, it doesn't recommend to run as super user. To resolve it, there is two ways to do it.

Option 1: Change the permission to npm's default directory.

Firstly, using npm config get prefix to get the npm directory. If it just /usr, switch to option 2.

Then using command sudo chown -R $(whoami) $(npm config get prefix)/{lib/node_modules,bin,share} to add premissions to user for only npm directories.

Option 2: Change npm's default directory to another directory

1. Make a directory for global installations:

   mkdir ~/.npm-global

2. Configure npm to use the new directory path:

   npm config set prefix '~/.npm-global'

3. Open or create a ~/.profile file and add this line:

   export PATH=~/.npm-global/bin:$PATH

4. Back on command line, update your system variables:

   source ~/.profile

To do a test, you could just download a package globally without using sudo

npm install node-g.raphael --save

If you are using MacOS, then you could use brew install node to reinstall nodejs. Homebrew would set things up with correct permissions.
